My '72 pre-L, a June 1972 car, had the molded space for the tire as well as holes for the Dzus clips.
Looking at the parts list, it would appear that there is one trunk style before car number 1285, a separate one until Service number 50103 (what is that?), then another one starting at number 9000. See item #48 on http://www.pim.net/18.2pim.html
